What is insulin
Insulin is a hormone secreted by the pancreas that plays an important role in regulating blood sugar levels in the human body. In recent years, with the increase in diabetic patients, insulin and its components have become a hot topic. This article will introduce in detail the components, functions and related hot topics of insulin.
Insulin ingredients
Insulin is a protein hormone, mainly composed of 51 amino acids, divided into A chain and B chain, connected by disulfide bonds. The following are the main components of insulin:
| Ingredients | Description |
|---|---|
| A chain | Composed of 21 amino acids and contains an intrachain disulfide bond |
| B chain | Composed of 30 amino acids, connected to the A chain through disulfide bonds |
| disulfide bond | The key structure connecting A chain and B chain to maintain insulin stability |
Insulin function
The main function of insulin is to regulate blood sugar levels and promote the absorption and utilization of glucose. The following are the main functions of insulin:
| Function | Mechanism of action |
|---|---|
| lower blood sugar | Promotes glucose uptake by liver, muscles and fat cells |
| Promote glycogen synthesis | Store glucose as glycogen in liver and muscles |
| Inhibit lipolysis | Reduces the release of free fatty acids from fat cells |
Hot topics and content in the past 10 days
Recently, hot topics about insulin mainly focus on the following aspects:
1.Insulin price controversy: Globally, the price of insulin has once again sparked discussion, especially in the United States, where the issue of overburdened patients has attracted much attention.
2.Research and development of new insulin: Scientists are developing longer-acting, more stable insulin preparations to improve the quality of life of people with diabetes.
3.The relationship between insulin and obesity: Research shows that insulin resistance is an important mechanism of obesity and type 2 diabetes, and related research has become a hot topic.
4.Innovation in insulin injection technology: New technologies like needle-free syringes and smart insulin pumps are changing the way people with diabetes are treated.
The future direction of insulin
With the advancement of science and technology, the research and application of insulin are also constantly making breakthroughs. The following are several possible future development directions:
| direction | potential impact |
|---|---|
| Oral insulin | Avoid painful injections and improve patient compliance |
| gene therapy | Restoring insulin secretion function through gene editing technology |
| Artificial Intelligence Assisted Management | Use AI to adjust insulin dosage in real time and optimize blood sugar control |
Summary
As an important hormone, insulin's composition and function are crucial to maintaining human health. With the advancement of medical technology, the research and application of insulin are constantly making breakthroughs, bringing more hope to diabetic patients. In the future, we look forward to more innovative technologies that can improve the experience and therapeutic effects of insulin.
